I suspect it is a space limittion more than anything that prevents most western shipyards from building multiple ships that size. ...... Cheap labor long ago reduced shipyards in most western countries to building military ships and some extremely spicalised or luxury ships.

You just contradicted yourself. Western shipyards aren't limited on space. If you have the demand, you can always get more space / capabilities / labor / raw materials. They are limited by demand.

No, when you are working on such a massive scale they really aren't simpler, the engineering and sheer weights alone are astronomical.

Not really, the numbers are larger but the math is very well understood. This is a very mature industry, perhaps the oldest manufacturing industry in the world. People have been building boats for thousands of years. Ship's aren't redesigned every time one is built either. The bulk of a ship is the exact same "U" profile. Design it once, copy it all down the length of the ship. The bow and the stern are the only complex parts, but contribute little to strength. The bow and stern are generally proven designs which are taken "off the shelf" and adapted to the application with only slight changes. Chopping off the back end of a ship (accommodation, engineering, and propulsion area), refurbishing it, and welding it to a brand new ship hull is not uncommon. Unlike with pleasure craft and cars, "style" has approximately 0 design influence in large ships. Everyone is honing in on the most hydrodynamic designs and you can't copyright the math which describes the curves on a ship.

I'm onboard the Tolteca right now, built in 1954/1955. When we were in drydock, the only difference between this ship and ships built much more recently is the distinct lack of a bulbous bow, and the use of diesel propulsion engines instead of a steam turbine.

Ship breaking is very tedious process: http://en.wikipedia.org/wiki/S... Why no to build-in capabilities for a ship to break itself easily?

Because it adds cost. When a ship has reached the end of its useful life, it's value is approximately the (ship mass * the price of steel). Labor in 3rd world countries is so cheap that it doesn't factor into the equation much. You would never see any return on that investment.

enough space to transport 864 million bananas I'm so happy to see we have finally converted to the banana scale. I've been waiting for this since horsepower was invented!

Maybe someone thought they were being clever, but in reality they are just very ignorant. Bananas are almost always transported by vertically-integrated companies who own their own ships. It's like this because generally Bananas are coming from a port which has little to ship aside from bananas, and the bananas generally go to a small number of special ripening warehouses where they ripen for a while. They're a kind of special cargo, not a general cargo to be put on any container ship. Just as an example, Dole owns at least 6 ships. Chiquita and the other banana companies almost always have their own ships too.

Sure, but what if a red LED is a natural evolution while blue LED, once thought impossible is the true revolutionary idea?

Well, maybe they looked at impact. For decades, LEDs were only used for status lights, power lights, and some other things. Switching from mini-incandecent bulbs for these purposes didn't really change much in the grand view of things. Switching out household lighting from incandecent to blue/white LED saves thousands of megawatts of electricity, and enables many impoverished people to have electric light for the first time ever. I went to North Korea this year and even in very remote areas with clearly impoverished people, solar panels, batteries, and LED lighting were very common. Bringing light to the people like that would be a lot more difficult without LED lighting.

And if you think that inexpensive, efficient lighting is not a big deal, try living without it for a week. The availability of inexpensive lighting has become so embedded in Western society that we can't imagine life without it. Think about what that means to the billions of poor people all over the world who are getting, or have gotten it, for the first time.

I've grown very tired of my apartment complex's saturated wireless spectrum (both 2.4 and 5) because everyone is right on top of each other and every apartment has one of three routers from the different ISP options.

Interesting. I didn't know that it was really possible to saturate the 5Ghz spectrum. 2.4 is easy with only having 3 non-overlapping channels, but 5Ghz has over twenty, and by default none of the channels overlap.

Last time I was in a dormitory I found over 20 networks within scanning range of the guy's room, but there was only ONE other network on the 5Ghz spectrum.

Read what the parent wrote- " the poor penetration of 5 GHz". Meaning it does not go through walls or other obstacles very well. Which is true. And a problem with deploying 5Ghz networks.

I have two pasports, as do many people. http://edition.cnn.com/2012/07...

It is nearly impossible to estimate how many U.S. citizens have dual -- or even triple -- citizenships, says Michael A. Olivas, an immigration professor at the University of Houston Law Center. [...] The number is likely well over 1 million, he says, and is probably several times that.

So, I can use one passport to go in and out of Cuba, Africa, Iraq, or wherever, and use the US passport for going in and out of the USA. How would they track that?

They can't even track a single US person with a single US passport. I took a trip to North Korea earlier this year. My father is an immigration inspector and looked at my record. According to the US government, I had a pleasant 10 days in Beijing.

Personal data harvesting for contextual ads and content should be a beautiful thing. They do it privately and securely, and it's all automated so that no human being actually learns anything about you.

So, are you shilling for the ad industry, or do you really believe this is supposed to be a good thing?

Sorry, but I'm not interested in your ads of any form, I'm not interested in targeted ads at all, and I don't trust the entities gathering this information with any of it, or that they won't abuse it.

So, screw your contextual advertising. I will continue to block every ad tracking site I can identify, block your ads, your web bugs, and everything else I can.

If you think letting unknown third parties collect information about you, put cookies on your machine so they can know everywhere else you go, run scripts, run Flash ... or pretty much anything else ... is a good idea, then you're either clueless, or getting paid from this.

I think your entire premise is flawed, or dishonest.

It could be a good thing. But usually it is abused. The ideal scenario is using targeting advertising to push someone over the edge when there was a 70+% chance of buying something anyway. If I go to Home Depot on a hot saturday morning, getting a text message coupon for the Dunkin Donuts on my way home would be great. Sadly, many advertising people are still stuck in 1960s and don't understand how to do unobtrusive advertising.

"CREE is selling 60w bulbs for $9"

Wow, a 60w LED bulb - how many lumens does that put out?

Feit electric has a similar 60W bulb for about $9 and it puts out 850 lumens. I bought a pile of them at Costco. With a $6 per bulb local utility company subsidy (Connecticut) they were $3 apiece. I like the color temperature a lot. I should have bought more. Also- I have been using 1 to 2 bulb "Y" adapters in any fixture where they will fit. Since LED's use so little power, there is no worry at all about exceeding the amperage limit of the wiring. Let it be bright!

Technical details on the turbine include; 200 lbs, 250 hp, 40,000h service life between overhauls (13+ years @ 8h / day.) The turbine has air bearings to eliminate wear, which implies a gas generator/power section arrangement to drive the generator, I believe.

A gas turbine is composed of two sections- a compressor and a power turbine. Probably they are using some compressor bleed air for the bearings (which is expensive, effeciency-wise). It still doesn't make sense to me though. Diesels in that size are much more efficient, more tolerant of abuse, more tolerant of contaminated fuels, and a lot cheaper to maintain. The only reason to use a gas turbine is when weight REALLY matters. We're talking about a garbage truck here. 100-200 more pounds for a diesel engine isn't going to be noticed. It may even balance out since a tank of diesel can likely be made lighter than a tank of compressed LNG.

That's messed up... Only 40 years of oil supply left, compared to 160 years natural gas and 400 years of coal.

No electricity should be generated via oil right now, and definitely not in 2050.

The amount of electricity generated using oil in the US is less than 1% and has been that way for decades. Oil is too expensive to burn compared to any other way of making electricity. The 1% used in the USA is generally in emergency cases where there is a heat wave / cold snap and demand outstrips the normal supply.
